ISF-IFI_long : Long panel file of taxpayers subject to the wealth tax and the real estate wealth tax

The Long panel ISF-IFI source is a panellised file of the ISF (Wealth Tax) and IFI (Real Estate Wealth Tax) declarations of tax households not subject to income tax declarations. This file contains information on the tax household (identifier, assets belonging to the tax household), on the tax declaration (type, year), on the different amounts payable by the tax households and on the different reductions applied to these amounts. Compared to the ISF-IFI file, this file contains additional information, in particular, details on the assets owned by the tax household, on the various reductions and exemptions applied to the amounts due.
